APPARATUS FOR MANIPULA'I'ING METAL INGOTS IN ROLLING-MILLS.

To all whom it may concern:

Be it known that I, EVAN WALTER DAVIES,

siding at Glamorganshire, Wales, have mvented new and usefulImprovements in Apparatus for Manipulating Metal Ingots inRolling-Mills, of which the a specification.

This invention relates to apparatus for manipulating metal ingots inrolling mills and refers more particularly adapted to work inconjunction with rollers for conveying ingots, rails and the likegenerally used in feeding the various kinds of rolling mills atmetallurgical works, such appliances bein more especially designs forturning the, ingots or other articles under treatment. y a

The apparatus is of the type comprising devices adapted to clutch theingot or turn it through a suitable angle about its longitudinal axis,and if desired to move it transversely to a convenient position on theconveying .mythe roller devices being reciprocated' simultaneous yorindependently in either direction across the ingotor other articleunder treatment conveying plane by means of mechanism controlled by theoperator.

My invention consists of an improved construction of apparatus of thebeforemem tioned description, constituting a self-concombination ofappliances for'the more effective handling of ingots or other articlesunder treatment mill, such clutchin I throughout their development tofinished ar-' ticles, the apparatus being moreover so constructed as toautomatically the varying size of any ingot or other article undertreatment when special care or. udgment on the part of ,thecontrollingoperator.

By suitably-operatmg the foregoing appak ratus an ingot or the like canbe clutched between the clutching devices, turned through the desiredangle and if desired transported as required.

And in order that my said invention may be better understood, 1 will nowproceed to describe the same with reference to the drawing accompanyingthis specification, in which Figure l is a Specification of LettersPatent. Application filed June 22, 1915.

The

At the other side ofthe apparatus is another piston rod 16, which works in a suitablerenewable bearing and is connected to a cross head 17, so as to run uponthe girders 2 in a similar manner to the cross head 6.
